Nyob rau hauv daim ntawv thov xws li laser ntau yam, lub hom phiaj kev txheeb xyuas, thiab LiDAR, Er: iav lasers tau dav siv vim lawv qhov muag kev nyab xeeb thiab kev ruaj ntseg siab. Nyob rau hauv cov nqe lus ntawm cov khoom configuration, lawv muaj peev xwm muab faib ua ob hom raws li seb lawv integrate ib tug beam expansion muaj nuj nqi: beam-expanded integrated lasers thiab non-beam-expanded lasers. Ob hom no sib txawv hauv cov qauv, kev ua tau zoo, thiab kev sib koom ua ke yooj yim.
1. Dab tsi yog Beam-Expanded Integrated Laser?
Ib qho kev sib txuas ntawm cov kab hluav taws xob yog hais txog lub laser uas sib txuas nrog lub teeb pom kev sib txuas ntawm cov khoom siv. Cov qauv no collimates lossis nthuav dav lub teeb pom kev sib txawv ntawm lub teeb laser, txhim kho cov kab teeb pom kev loj thiab lub zog faib tawm mus ntev.
Cov yam ntxwv tseem ceeb muaj xws li:
- Collimated output beam nrog qhov chaw me me ntawm qhov ntev
- Integrated qauv uas tshem tawm qhov xav tau rau sab nraud beam expanders
- Txhim kho qhov kev sib koom ua ke thiab kev ruaj ntseg tag nrho
2. Dab tsi yog Qhov Tsis-Beam-Expanded Laser?
Nyob rau hauv sib piv, ib tug non-beam-expanded laser tsis suav nrog ib tug sab hauv beam expansion optical module. Nws emits ib tug raw, divergent laser beam, thiab yuav tsum tau sab nraud optical Cheebtsam (xws li beam expanders los yog collimating lo ntsiab muag) tswj beam txoj kab uas hla.
Cov yam ntxwv tseem ceeb muaj xws li:
- Ntau compact module tsim, zoo tagnrho rau qhov chaw-constrained ib puag ncig
- Yooj yim dua, tso cai rau cov neeg siv xaiv cov kev cai kho qhov muag
- Tus nqi qis dua, tsim nyog rau cov ntawv thov uas kab teeb duab ntawm qhov deb tsis tshua muaj qhov tseem ceeb
3. Kev sib piv ntawm ob
①Beam Divergence
Beam-expanded integrated lasers muaj ib tug me me beam divergence (feem ntau <1 mrad), thaum non-beam-expanded lasers muaj ib tug loj divergence (feem ntau 2-10 mas).
②Beam Spot Shape
Beam-expanded lasers tsim ib tug collimated thiab ruaj khov qhov chaw zoo, whereas non-beam-expanded lasers emit ib tug ntau divergent beam nrog ib tug tsis tu ncua qhov chaw ntawm qhov ntev.
③Ib qho yooj yim ntawm installation thiab Alignment
Beam-expanded lasers yog yooj yim rau nruab thiab ua kom zoo vim tsis muaj sab nraud beam expander yuav tsum tau. Nyob rau hauv sib piv, tsis-nqaj-ntev lasers yuav tsum tau ntxiv kho qhov muag Cheebtsam thiab complex kev sib raug zoo.
④Nqi
Beam-expanded lasers kuj kim dua, thaum uas tsis yog-beam-expanded lasers yog tus nqi ntau dua.
⑤Module Loj
Beam-expanded laser modules yog me ntsis loj dua, whereas non-beam-expanded modules yog ntau compact.
4. Daim ntawv thov Scenario piv
①Beam-Expanded Integrated Lasers
- Ntev-ntev laser ranging systems (piv txwv li,> 3 km): Lub nqaj yog ntau concentrated, uas txhim kho ncha teeb pom kev zoo.
- Laser lub hom phiaj xaiv cov tshuab: Yuav tsum muaj qhov tseeb thiab meej qhov projection hla qhov ntev.
- High-end integrated electro-optical platforms: Xav tau cov qauv kev ruaj ntseg thiab qib siab ntawm kev koom ua ke.
②Tsis-Beam-Expanded Lasers
- Handheld rangefinder modules: Yuav tsum muaj qhov loj me thiab lub teeb yuag tsim, feem ntau yog siv luv luv (<500 m).
- UAVs/robotic obstacle zam systems: Chaw-constrained ib puag ncig tau txais txiaj ntsig los ntawm kev hloov pauv tau yooj yim.
- Tus nqi-rhiab loj tsim cov phiaj xwm: Xws li cov neeg siv khoom-qib rangefinders thiab compact LiDAR modules.
5. Yuav ua li cas xaiv txoj cai Laser?
Thaum xaiv Er: iav laser, peb xav kom cov neeg siv xav txog cov hauv qab no:
①Daim ntawv thov nyob deb: Rau kev siv ntev ntev, cov qauv beam-expanded yog nyiam; rau cov kev xav tau luv luv, cov qauv uas tsis yog-nqaj nthuav dav tuaj yeem txaus.
②System integration complexity: Yog hais tias kho qhov muag alignment peev xwm muaj tsawg, beam-expanded integrated khoom raug pom zoo kom yooj yim teeb.
③Beam precision yuav tsum tau: Rau high-precision ntsuas daim ntaub ntawv, lasers nrog tsawg beam divergence raug pom zoo.
④Cov khoom loj thiab qhov chaw txwv: Rau cov tshuab compact, cov qauv tsis-nqaj-ntev yog feem ntau tsim nyog.
6. Cov lus xaus
Txawm hais tias beam-expanded thiab non-beam-expanded Er: iav lasers qhia tib lub core emission technology, lawv txawv optical tso zis configurations ua rau txawv kev ua tau zoo yam ntxwv thiab daim ntawv thov haum. Kev nkag siab txog qhov zoo thiab kev lag luam tawm ntawm txhua hom pab cov neeg siv kev txawj ntse, kev xaiv tsim tau zoo dua thiab txhim kho tag nrho cov kev ua tau zoo thiab kev ruaj ntseg.
Peb lub tuam txhab tau ntev tau mob siab rau R & D thiab customization ntawm Er: iav laser khoom. Peb muab ntau hom kab-nthuav dav thiab tsis-nqaj-nrhiav kev teeb tsa thoob plaws ntau qib zog. Xav tias dawb hu rau peb kom paub ntau ntxiv txog cov ntsiab lus thiab cov lus qhia xaiv uas haum rau koj daim ntawv thov.
